摘要
设计一种恒压充电器,本质是由UC3844控制的双管正激式开关电源,本文给出了主电路和控制电路的拓扑结构,并对其工作原理进行了详细分析,通过实验对其效果进行了验证,达到设计要求。
The design of a constant voltage charger, which is a sort of dual-transistor forward switching power supply realized by UC3844 as a core unit, is presented. The topologies of main circuit and control circuit are provided under exhaust analysis in principles Good agreement is achieved between predictions and measurements, and all the technical indexes are fulfilled.
